What should such a self-report essentially contain?

A self-report should essentially contain clear and concise information about the individual's experiences, thoughts, feelings, or behaviors regarding a specific topic. It should include relevant context, such as the timeframe or circumstances surrounding the experiences being reported. Additionally, it should be structured to allow for honest reflection, often incorporating both qualitative and quantitative elements to provide a comprehensive understanding of the individual's perspective. Finally, it should ensure clarity and avoid ambiguity to facilitate accurate interpretation.
